-### Subscribe to system theme changes
-You can subscribe to system theme changes by using the `subscribe` function. This function returns a stream of `Mode` values. The stream will emit a new value whenever the system theme changes.
-
-> [!WARNING]
-> The `subscribe` function is not yet supported on macOS, Windows, and WebAssembly.
-> Using it will result in an empty stream.

-use futures_lite::StreamExt;

-async fn main() -> Result<(), dark_light::Error> {
-    let mut stream = dark_light::subscribe().await?;
-    while let Some(mode) = stream.next().await {
-        println!("System mode changed: {:?}", mode);
-    }
-    Ok(())
